TABULATING ATTACi-EMENT FUR TYPE WRlTEF-Zd.

SPECIFICATION forming part of Letters Patent No. 691,130, dated January Id, 1902. Application filed September 8, 1900. serial No. 29,417. (No model.)

' vice for,type-\vriting machines of the traveling-paper carriage class, of which the Remington machine is a well-known example.

Tabulating attachments are used to assist the operator in writing columns of figures, when unless some mechanical assistant is provided it becomes necessary to stop the paper-carriage manuallyat suitable points, so

i 'that in writing a column of figures the decimal-points shall appear in true vertical column. In so doing the'operator is obliged to verify visually the location of the paper-carriage before'writing each figure 'in the column, and although the mechanical tabulating devices heretofore provided assist in this operation to the extent of providing afixed intermediate stop which arrests the paper-carrings at a point short-of its normal limitof travel'the operator is still obliged to make docasional visual verification when the denominations of figures in the column change from tens to hundreds and thousands, (he.

My improved tabulating attachment provides means whereby correct tabulation of a column of figures may be made without visual reference to the paper in the machine and whereby the machine isleft entirely free'to do all its ordinary work without removal or adjustment of the tabulating attachment. It also contains a device-for relieving the machine of the shocks which are'occasioned when, as in some tabulating attachments, the paper carriage is released from its detent and al. lowed to advance without hindrance until it brings up against astop on the tabulating attachment.

too well known .to require illustrative or detailed description. Obviously, however, my invention is adapted to be applied toanytypewriting machine which employs a paper-carwhich exerts a constant effort to pull the paper-carriage forward and is restrained normally by the step-by-step feed mechanism, which permits the carriage draft to act only for short spaces at intervals.

In the drawings, Figure 1 represents a front elevation of my tabulating attachment and portions of the machineframe and paper-carriage; Fig. 2, aside elevation of my tabulating attachment with the machine-frame and paper-carriage partially shown; Fig. 3, a rear elevation of the tabulating attachment and a portion of. the paper-carriage rack-bar; Fig.

This ab- 4., a plan view of the tabulating attachment with portions of .the paper-carriage broken away, and Fig. 5 shows in perspective the yielding stop employed in connection with the stop-rack shown in the other figures.

The frame A of the Remington No. 6 typewriting machine provides by its regular construction convenient means for securing my tabulating attachment to the machine. The tabulating attachment is mounted upon a plate E, which is perforated to receive the screw b, Figs. 2 and a, which secures the plate to the machine-frame A, andis also perforated or recessed, as at a, so as to slip over a stud ior boss on the machine-frame.

A stop-rack d is fitted to slide in a guide E 1n the raised portion E which is integral with or secured to the plate E. This raised portion is cut away at one end at its rear side, as shown in Fig. 4, so that the gear-wheel e can mesh with the teeth in the rack 01. The gear-wheel e is rotatively mounted upon the plate E and is actuated at the will of the operator by the -The stop F,

toothed wheel 6', which is mounted upon the stud c and secured to the knurled disk 6. The sliding rack d lies parallel with the axis of the paper-carriage just in front of the letter-space feed-rack r, Fig. 4. A stop F, (shown in detail in Fig. 5,) provided with forked legsf f isadapted to be placed upon the stop-rack (I, said legs straddling the central upper portion (.1 of the stop-bar d, the prongs of the legs extending into the spaces d between the teeth of the stop-rack. The stop F is shown in the drawings as specially designed to afford a cushioned contact for the paper-carriage; but'for many purposes a simple clip adapted to rest between the teeth of the stop-rack dwill serve equally well. as herein shown, consists of a dash-pot, in which slides the piston f, attached to the stem or piston-rod f whose outer end is laterally bent at f and terminatesin astop-fingerf. The piston f should be prevented from turning. by the use of a feather-and-groove device or some equivalent with the toothed wheel, (not show'i1,) which.

means, so that the position of the fingerfinay remain constant with reference to the path of travel of the paper-carriage; If desired,

vents f are provided in thedash-pot cylinder. A light springf Fig. 3, serves to return the piston f to its outerposition when released from the pressure of the paper-carriage. v

A stop or detent R is secured to the letterspacefeed-rack r by a screw 1' and hook W. This detent is curved at its lower left-hand end, as viewed in Fig. 1, terminating in a detent-finger r (Shown in Figs. 2 and t.)

The letter-space feed mack r cooperates is connected with the step-by-step feed movement of the machine, so that when the papercarriage is in positibn for Writing the normal step-by-s'tep feed is communicated to the paper-carriage by means of the feeding mechanism, toothed wheel, and letter-space feedrack '1. When, however, it is desired to move the paper-carriage in the direction of its normal step-by-step movement without employing the step-by-step feed, the usual release-lever L comes into play. The operatordepresses the tread Z and raises the oppo site end I of the lever L, lifts the letter-space feed-rack out of mesh with its toothed wheel,

' and thus leaves the carriage free to move under the stress of its draft-spring, except as controlled by the hand of the operator. I

. have shown the release-leverL as offset at Z so that in the normal movement of the machine it may pass by the stop F without interfering with the same. The letter-space feedrack is pivoted upon the paper-carriage B at B Fig. 4, just in the rear'of the guide-rail O,'where the usual pivot-rod r and depression-spring r are located.

The relative positions of the letter-space feed-rack pivot R and the detent-finger r are such that the liftifig movement of the letter-space feed-rack under the in ence of the release-lever L causes the detent-finger r to move toward the-front of the machine in an arc of a circle. This movement advances the end of the detent-finger so that it is arrested by the stop-finger f when the movement of the paper-carriage brings the detentfinger r to the position occupied by the stop. When the releasing-lever L ceases to act upon the letter-space feed-rack, which then falls to its normal position and meshes with its gear connections with the letter-space feed movements, the detent is retired out of its path of contact with the stop-fingerf.

The stop F maybe placed at will upon any part of the stop-rack d, or, if it is desired, two or more stops F may be employed and be located at desired intervals upon the stop-rack. This arrangement permits the type-writing mechanism to perform all its normal functions without hindrance. Only when the operator desires to bring the paper-carriage ,to rest at a point determined by the location of the stop F upon the stop-rack can the stop and detent coact with each other to arrest the carriage.

During all the normal letterspace and space-bar movements the detent-finger 7' passes by the stop-finger f, and so, also, when the carriage is returned to position for the beginning of a line these members of my tabulating attachment remain inactive.

By providing a stop or stops F, as shown and described above, the paper-carriagecan be arrested at a predetermined point or points, and accurate tabulation of a column or columns of figures may thus be facilitated. In order, however, to facilitate still further the accurate tabulation of columns of figures, I

have provided for an adjustable movement of the stop-rack d itself in the direction of its length. The knurled disk 6, toothed wheel 0, and gear-wheel e have been alluded to before. The teeth in the gear-wheel e mesh with the lower tooth-space (Z of the stop-rack d. -A detent c pivoted at c upon the plate E, is urged into contact with the gear-wheel e by spring c.

The toothed wheel (2' is am utilated gearhaving in this instance only four-teeth. These teeth perform a double function. \Vhen the knurled disk 0 and toothed wheel 6 are rotated together, one of the teeth of the wheel -e makes contact with and moves the detent a out of contact with the teeth in the gearwheel 6 and holds it so removed while the .neXt tooth in the wheel c meshes with the gear-wheel e and moves it the space of one tooth in the direction desired by the opera.- tor. This of course advances the stop-rack d in either direction by the space of one tooth, these tooth-spaccs being equal to the letter-space of the type Writing machine. Thus the point of arrest oil the paper-carriage bya stop F may be changed at will without obliging the operator to shift the position of the stop upon the stop-rack. 'lhis mechan ical feature performs its functions in connection with the index scale and pointer, which appear upon the side of the tabulating at: tachment toward the operator of the machine.

An index'ma'rker d Figs. 1 and 4, is .secured to the stop-rack and points to an in dex-scale e which is marked upon the raised portion e of the plate E. This indexscale,

as'shown in Figs. land t, represents the in tons, with decimals representing cents, the

operator places the stop F ata convenient point on the stop-rackand then by the aid of the disk (2 moves the stop-rack until the index-marker d points to the fourth mark on the right of the decimal-point on theinden-scale 'e.

Movement of the carriage, upon release of the lever L will always be arrested by the stopF at the same point. In writing a sumv having four figures before the decimal the operator begins immediately to write the figures after the stop F has arrested the carriage. "When figure in the hundreds is reached, the operator first strikes the spacebar and then Writes the three figures before the decimal, andif the figure is in tens strikes the space-bar twice, and so on. When this column is inspected, it will be found that all the figures are accurately tabulated withthe column of decimal-points in a true vertical line. No verification is required-except as afforded by the index-marker d and'its position with relation to the index-scales".

If a column of figures contains, say, most of the sums in hundreds, with very few in the thousands, and the index is set for hundreds, the operator need not return the carriage after it is arrested by the stop and then verify the position of the carriage by raising it, but has only to advance the stop-rack one tooth before moving the paper-carriage to the stop. When the sum of larger denomination isputdown, the stop-rack can then be re-' turned to its convenient normal position for the column being written.

Tabulating attachments have been used for type-Writing machines in which the carriage is released'by pressing a special key, so that the carriage is moved quite violently into contact with the stop-Which forms part of the tabnlating attachment. This mode of operation is quick, but results in unpleasant: jar to the machine, and in order to prevent this condition of things I have provided the dashpot stop above described, which maybe used either with a tabulating attachment which embodies my invention or with other devices designed to accomplish a similar purpose.
